A mortgage Loan Estimate does not come with one universal expiration period. It contains estimated closing costs with their own disclosed expiration date and time, while the interest rate may have a separate lock period. A 10-business-day rule also matters, but it concerns expressing intent to proceed—not a promise that every quoted term stays fixed for 10 days. Check the dates and rate-lock status on your actual form, and confirm lender-specific terms directly.
What “how long a Loan Estimate lasts” actually means
A Loan Estimate is a standardized disclosure of key mortgage terms and estimated costs. It helps you compare offers, but it is not a loan approval and does not commit you to borrowing from that lender. The CFPB says the loan commitment comes with the final closing documents. The form is a snapshot of the terms and estimates disclosed at that point; some details may change under circumstances permitted by the applicable rules. See the CFPB’s Loan Estimate guidance.

People often ask how long a mortgage quote is “good for” as if the form has a single clock. In practice, three separate timing questions are involved:

| Interest-rate lock | A separate agreement that may hold the interest rate for a specified period, subject to its terms and conditions. | Whether the rate is locked, when the lock ends, and what happens if closing is delayed. |
These clocks can have different end dates. Do not assume that an unexpired cost estimate means your rate is locked, or that a rate lock guarantees every fee will stay unchanged.

What the 10-business-day rule does—and does not—do
If you do not express intent to proceed within 10 business days after the lender sends the Loan Estimate, the lender can treat the application as incomplete and close it. CFPB guidance also explains that a lender may provide a revised estimate for good-faith comparison purposes if you indicate intent to proceed more than 10 business days after the original disclosures were provided. The rule is about the application and disclosure timeline; it is not a blanket guarantee that all quoted terms are fixed for those 10 days. The CFPB describes this in its guidance on choosing a loan offer and in Regulation Z, 12 CFR § 1026.19.
There is also a separate delivery deadline at the beginning of the process. Under CFPB guidance, a lender generally must deliver the Loan Estimate within three business days after receiving the six key pieces of information that make up an application. That delivery timing does not create a three-day or 10-day rate guarantee. The CFPB’s Loan Estimate review guidance covers the delivery period and how to examine the form.
Where to find the expiration and rate-lock information
Estimated closing-cost expiration
Look for the expiration date and time printed on the Loan Estimate. Regulation Z requires the form to state “the date and time (including the applicable time zone) at which estimated closing costs expire.” That is the form’s disclosed window for those estimated costs; it is not automatically an interest-rate lock. The requirement appears in 12 CFR § 1026.37(a)(13).

Rate-lock status
On the first page, check whether the interest rate is locked and, if so, the date through which the lock applies. CFPB guidance states, “If your rate is not locked, it can change at any time.” A lock generally protects the stated rate between offer and closing if closing occurs within the specified period and the application does not change in a way that affects the agreement. It does not mean every cost or loan term is immune from change. Review the lender’s lock agreement as well as the Loan Estimate.
The CFPB says rate locks are often offered for 30, 45, or 60 days, with longer periods sometimes available. These are typical periods described in its consumer guidance, not a promise that a particular lender offers each duration or that every lock has identical conditions. Ask the lender directly about availability, cost, and terms. See the CFPB’s explanation of mortgage rate locks.
What a rate lock covers—and what it may cost you
A rate lock is a time-limited agreement, not an open-ended promise. Its protection depends on the stated lock period and conditions. If the loan does not close before the lock ends, ask what extension is available, how much it costs, and whether the lender will extend it at all. Do not assume an extension is automatic. The CFPB notes that extending a lock can cost money.

A lock also involves a trade-off: if market rates fall, you may not benefit from the lower rate under the terms of your lock. Ask the lender whether the agreement includes any option to adjust to a lower rate and what conditions or costs apply; do not assume such an option exists. Get the response in writing and compare it with the lock terms you received.

If a later lock changes the interest rate, points, or lender credits, those changes may appear on a revised Loan Estimate. A low initial rate is therefore not a reliable basis for comparing lenders unless you also know whether it is locked and on what terms.
Why a lender may issue a revised Loan Estimate
A revised form may reflect newly discovered or changed information rather than an arbitrary decision to alter your offer. CFPB examples include a change in loan type or down payment, a low appraisal, a change in credit score, inability to verify income, or a later rate lock that changes points or lender credits. The CFPB’s guidance on revised Loan Estimates and on a higher rate or increased costs explains examples and what to review.

The CFPB says it is illegal for a lender to deliberately underestimate charges to surprise a borrower later. At the same time, some revisions are permitted when new or different information is discovered. Whether a particular fee or revision is allowed depends on the facts, timing, loan product, and applicable fee rules. An unexpected increase alone does not establish that a lender broke the law.
How to review a revision
- Keep both forms. Compare the revised Loan Estimate with the original rather than relying on a verbal summary.
- Ask what changed. Request the specific new or different information that led to the revision, when the lender learned it, and the reason the form was reissued.
- Identify the financial effect. Check the loan amount, interest rate, monthly payment, loan features, points, lender credits, estimated closing costs, and cash to close.
- Check any rate-lock connection. If the revision followed a lock or a change to the lock, ask how that affected the rate, points, credits, or expiration date.
- Ask for a written explanation. Keep the response with the forms so you can assess the timeline and compare the stated reason against the revised figures.
If the explanation does not resolve your concern, consider speaking with a qualified housing counselor or attorney. A conclusion about legality requires reviewing the actual forms, timeline, loan type, and reason given; the CFPB’s consumer guidance is not a substitute for evaluating your specific file.
How to compare Loan Estimates before choosing a lender
Compare offers on the same basis. If one estimate assumes a different loan type or down payment, the rates and costs may not be an apples-to-apples comparison. The CFPB recommends comparing offers from multiple lenders and reviewing the same categories across the forms. Its loan-offer comparison guidance and Loan Estimate review guide explain what to examine.

- Loan type and down payment: Make sure the offers assume comparable loan products and down-payment amounts.
- Interest rate and lock status: Record the rate, whether it is locked, and the lock’s end date.
- Lock duration and extension: Ask how long the lock lasts, what an extension costs, whether an extension is available, and what applies if closing is delayed.
- Points and lender credits: Compare these alongside the rate; a rate change can be accompanied by different points or credits.
- Estimated closing costs and cash to close: Review both categories instead of focusing only on the interest rate.
- Monthly payment and loan features: Compare the payment and the structure of the loan, not merely the headline rate.
- Expiration dates: Note the estimated closing-cost expiration separately from any rate-lock end date.
Ask each lender to explain any difference you cannot account for. A lower rate may not be the better offer if it comes with different points, credits, costs, or lock terms. The objective is to compare equivalent loans and understand what is protected, for how long, and at what cost.
Questions to ask your lender before you proceed
- Is the interest rate on this Loan Estimate locked or floating?
- If it is locked, what date and time does the lock end, and what conditions could affect it?
- How much would an extension cost, how long could it extend the lock, and is an extension guaranteed?
- What happens to the rate and costs if closing is delayed beyond the lock period?
- What date, time, and time zone apply to the estimated closing-cost expiration printed on this form?
- If I receive a revised estimate, what changed and how does that affect my payment and cash to close?
- How can I communicate intent to proceed, and how will you confirm receipt?
Keep the Loan Estimate, any rate-lock agreement, revised forms, and written answers together. They provide the clearest record of which terms were estimated, which were locked, and what changed as the application progressed.
Important scope limits
This guidance concerns U.S. mortgage transactions generally covered by the CFPB’s Loan Estimate and Closing Disclosure process. CFPB guidance notes that some products, including reverse mortgages and home equity lines of credit (HELOCs), follow different disclosure pathways. Do not apply the timing or form discussion here to those products without checking their specific disclosure rules.
